I-IEEL-SEAT-FITTING MACHINE.

Application filed November 15, 192. `Sera1 No. 148,453.

This invention relates to machines for use in the manufactureof shoes and isv illustrated vas embodied in a. heel-seat fitting. machine arranged also to Vmold and'smooth the counter portions of .shoes during the performance of the heel-seat fitting operation. This application is a continuation in part of my copending application Serial No. 46,- l711, Vfiled .Iuly 29, 1925. f In the manufacture of shoes to which wood yheels are to be attached, it is usual toY trim surplus stock Afrom the heel-seat portions of their soles to cause the heel-seat portions of the shoes to fitthe concave attaching surfaces ofthe heels in such a way. that the y edges of the heels may engage the shoe uppers closely adjacent `tothe edges of their soles so that the edges ofthe heel-seat portions of the soles are not visible in the finished shoes. .As a part of this operation, a pair of shoulders are often formed at the heel-breast line of the sole against which the breast of the heel is positioned when the heel is attached. These shoulders serve as abut.

ments to support the heel against forward displacement while it is being attached and to conceal any minor variation between the convex curvature of the forward portion of the heel-seat and the concave curvatureof the corresponding portion of the heel. It is an object of the present invention to provide improved mechanism for cutting such heelbreast-receiving shoulders in the soles of shoes. As illustrated, these shoulders are cut by'a pair of knives carried byfingers mounted upon a pivot substantially at right angles to the sole of the shoe operated upon and carried by an arm extending forward of the heel-breast'line of itsV sole. Simple mech- 40 anism is provided to Swing the knife-carrying ngers about .their pivot so as to cause t-he knives to cut the heel-breast-receiving shoulders in the sole.

In order to improvethe appearance of the shoesoperated upon, a feature of the invention comprises the combination of means for cutting heel-breastfreceiving shoulders or other abutments at or adjacent. to the heel breast lines of the soles of shoes with a mold arranged to contact with the counter 'portions of the uppers of theshoes during the cutting of said shoulders or abutments to smooth the upper leather of the counter portions of the shoes and to eliminate any wrinkles that may be present. Y

With the above and other objects and features in view, the invention will now be described with reference to the accompanying drawings and pointed out in the claims.

In the drawings,

Fig. 1 is a perspective view of a portion of a heel-seat fitting machine embodyingthe present invention;

Fig. 2 is a perspective view, on a larger scale, of the shoulder-cutting and the counter-molding` portions of the machine;

- Fig. 3 is a cross-sectional view on the line III-Ill of Fig. 2; and

Fig. 4 illustrates the heel portion of a shoe after the-completion of the heel-seat fitting and molding operation, showing also the chip detached from the sole in the heelseat fitting operation.

The invention is illustrated herein as embodied in a heel-seat fitting machine of the type illustratedl in an application for Letters Patent of the United States filed March 9, 1925, in the yname of William C. Stewart and Harry L. Hood, and having Serial No. 14,137. Since the general organization of the machine may conveniently be as illustrated in said application, the drawings of this application disclose no more of that machine than is necessary for a full understanding of the present invention. L

.In accordance with the showing of said application, Serial No.`14,137, the illustrated ymachine is providedwith a pair of crease plates 10 mountedin a table 12 for pivotal movement about a point 14 substantially in alinement with the back seam of the shoe v to be `operated upon, shown at 16, which .is

carried by a suitable work support 1S pivoted` at .19 for movement into and out of are provided with thin edges 20 (best shown 1 in Figs. 2 and 3) arranged to enter the rand 'crease Vof the shoe to be operated upon and to support the peripheral portion of the `lhcelfseatof .thesolefcfw the shoe during the Q Sli heelseat litting` operation. In accordance also with a usua'l practice in the construction of heel-seat fitting machines, appropriate means` which iorni no part of the present invention and are therefore not shown in the drawings, may be supplied, as illustrated, for example, :in said application, Serial No. 14,137, for lieveling;r the peripheral portion ot the heehseat ot the sole of the shoe 1G.

The crease plates of the illustrated niachine carry on their lower surface or are formed with mold members 222 shaped to appl)v pressure to the counter portion of the upper of the shoe operated upon, thesemold members being moved With the crease plates about point 14 in alinen'ient with the back seam oi the shoe. To cause mold ineinbers 272 more el'l'ecl'ivellv toshape the shoe upper to the last 23 upon which it is mounted and to remove `any Wrinkles which may be present, they are` provided with electric resistance units 24C by which thev may be heated. As illustrated, mold members 22 are hollow and resistance units Qt are housed therein. t p

larried by the rt'ralne of the machine is an arm ZG projectino' over the `shank of the shoe upon the Worth support 1S forwardly oi its heel-breast line. Carried by a pivot QS mounted near the forward end of arm 26 are a pair ol lingers B0, each of which carries at its 'forward end a knife hladc or cutter -B- l arranged, when arms 30 and 352 are swung' about pivot Q8, to cut heel-breastreceiving' shoulders 36 at the breast line oi the sole oil the shoe, as shown in Fig. Preferably, and as illustrated in Fig. 2, the portions of the cutting edges of b'lades 34 toward the center line of the shoe are sonic what inclined so that the portions of the cuts nearer to the center line of the shoe do not extend through the full depth of the solo but become gradually shallower, finally emerging at the tread surface of the sole, as shown at 3S in Fig.` el. In order to swingl lingers 32 about pivot 2S, each of those fingers is provided with" a pin positioned in one of a pair of slots a2 carried bv a bar let mounted for sliding more ment in Ways formed in or carried by the trarne oi the machine, as shown at 45, Fig. l. Suitable mechanism ior moving bar Llfl back and forth is provided comprising a treadleoperated rod 46 connected at its upper end to a bell cranklever 4S ulcruined at 5() to the frame oi the machine and connected by a link 52 Ywith bar 44. Thus the depression of rod i6 moi'ies bar 44 in a direction to swing; knife bladesi toward each other, eutting heel-breastfreceiving shoulders 36 in the sole. To liinit the `1`nove1nent of lrn'ife blades 34 toward eachother and to prevent "-the cuts made by these knives from extending "too far toward "the 'center line of the sole, finger "30 is "provided vv-nh a stop illustrated as aainstable screw 54 arranged to impinge `upon linger 3:2 at the end oi the desired move mentI of knife blades 34.

In the operation of the machine, a shoe mounted upon a last is placed upon work f support 18 and is moved rearwardly into engageinent With crease plates l() the thin edges 2() oi' which are caused to enter the rand crease of the shoe to support the edge of its sole. Mold members 22 thus engage the counter portion of the shoe upper and smooth out any Wrinkles or other irregularities present. lhile the shoe is thus held, the peripheral portion of the heel-seat may be suitably beveled and" heel'fbreast-receiving cuts are made by sivinglriiiur fingers Si), and cutters 341 about pivot 28, thus concluding' the ope ation and removing,V a horseshoeshaped chip, as indicated at 56, in Fig. 4.
